United States JALOUSIE LOUVRE END CLIP Application February 7, 1957,Serial No. 638,775

6 Claims. (CI. 2062) The present invention relates to jalousie windowsand doors, and more particularly to an improved end clip for mountingthe louvres of the jalousie for pivotal movement in the frame.

The present invention provides an improved clip con struction whichaffords ready removal of the louvre from the clip, but which insuresfirm engagement of the louvre against accidental displacement duringnormal operation.

The present invention provides a louvre end clip of improvedconstruction which is of simple manufacture and is readily assembled.

More specifically the present invention provides a louvre end clip whichengages the louvre in the central part thereof, prevents movement of theclip longitudinally of the louvre and holds the louvre itself againstlateral displacement.

All the objects and the various features and details of the constructionand operation of the invention .are more fully set forth hereinafterwith reference to the accompanying drawing, in whicht Fig. l is athumb-nail sketch in perspective of a jalousie wind-ow as seen from theexterior;

Fig. 2 is a fragmentary view in plan of a louvre end clip made inaccordance with the invention, mounted in the frame, and engaged on theend portion of a louvre of the jalousie;

Fig. 3 is a sectional view taken on the line 3--3 of Fig. 2 showing theend clip in side elevation;

Fig. 4 is a fragmentary view in inverted plan of the end clip shown inFig. 2;

Fig. 5 is a sectional view taken on the line 55 of Fig. 3;

Fig. 6 is a view similar to Fig. 3 with the louvre removed, and

Figs. 7 and 8 are detached perspective views of the elements of an endclip made in accordance with the present invention.

Referring to the drawing, an end clip assembly 11 made in accordancewith the present invention is shown mounted for pivotal movement asindicated at 12 on a frame and supporting a louvre 24. Actuator means isprovided to pivotally displace the clip 11 simultaneously with thedisplacement of the clips mounting the other louvres. In the presentinstance the actuator means comprises a channel member 13 pivotallymounted on the end clip as indicated at 14. The end clip assembly 11comprises an outside member 20 having a vertically disposed side plate21 receiving the respective pivotal mounting means 12 and 14. The member20 is provided with an elongated flange 22 at an edge of the plate 21overlying the outer surface 23 of the end portion of the louvre 24. Theflange 22 terminates at one end in a lip 25 which engages the lower sideedge of the louvre 24 and supports it against downward displacement.

Means is provided to bias the louvre 24 against the flange 22. To thisend a support bracket is mounted on F atent "ice the end plate 21 of themember 20 in inwardly spaced relation from the inner surface 27 of thelouvre. The bracket 26 comprises an elongated web substantially parallelto the flange 22 and having a longitudinal groove 28 formed therein. Theweb of the bracket 26 terminates at one end in a leg portion 31projecting toward the flange 22 at the end of the web adjacent the lip25. An aperture 32 is provided in the leg portion 31 in registry withthe groove 28.

In accordance with the invention, a spring element 35 is mounted on thebracket 26 and resiliently engages against the inner surface 27 of thelouvre to bias the louvre against the flange 22. To this end the springelement 35 comprises an elongated resilient strip having an angularinwardly-bowedsection 36 intermediate the ends thereof. As shown in Fig.3, the inwardly-bowed section engages the inner surface 27 of the louvrewhen the strip 35 is assembled to the bracket 26. The strip is formedwith a reinforcing rib 37 disposed longitudinally of the strip in thebowed section and extending beyond the bowed section at its oppositeends.

The strip 35 is adapted to be mounted or anchored at one end in thebracket 26 and is operable to be engaged at the other end with the sideedge of the louvre 24 opposite to the edge which engages against the lip25. The rib 37 extends into the anchoring end 38 of the strip and isadapted to project into the groove 28 of the mounting bracket 26. At theextremity of the anchoring end 38, the strip 35 is formed with anendwise projecting finger 39. The finger 39 engages in the aperture 32to prevent lateral displacement of the end portion 38 relative to thebracket 26. The interengagement of the rib 37 and the groove 28 alsoassists in preventing lateral displacement of the strip 35.

To further insure against lateral displacement of the strip 35, thebracket 26 is provided with an ear 41 spaced laterally from the groove28 and projecting toward the flange 22 adjacent the end of the webremote from the leg 31. The car 41 engages in an aperture 42 formed inthe strip 35 adjacent one edge thereof. A similar aperture is providedat 43 to register with a leg similar to the leg 41 formed in an end clipof the other hand for mounting at the opposite end of the louvre. Thus,when the strip is assembled to the bracket, it is held againstinadvertent displacement. However, as shown in broken lines in Fig. 6,the strip may be displaced from engagement with the bracket 26 byflexing the same inwardly to free the aperture 42 from the ear 41 and toafford withdrawal of the finger 39 from the aperture 32.

Means is provided to engage the side edge of the louvre 24 which isremote from the inturned lip 25 of the end member 11. To this end theremote extremity of the spring strip 35 is formed with an inturned lip45 operable to engage against the adjacent edge of the louvre 24. Asstated above, the element 35 is preferably formed of spring metal orsimilar resilient material and is supported at one end in the mountingbracket 26. Thus, the lip 45 may be displaced outwardly away from theinner face 27 of the louvre 24 to afford lateral displacement of thelouvre for cleaning or repair. This operation is shown in broken linesin Fig. 3. It is noted that the spring element 35 is removably mountedon the bracket 26 so that in the event of over-sized or undersizedlouvres, a correspondingly over-sized or undersized spring strip may hesubstituted for the spring strip 35. In this way, the end clip affordsfirm engagement of the louvre at opposite side edges thereof.

The end mounting of the louvre of the present invention provides anassembly which is readily assembled and economically manufactured. Theassembly may accommodate louvres of varying sizes without substantialmodifications and is fully effective to prevent rattling of the louvrein the end clip and prevent inadvertent lateral displacement of thelouvre out of engagement with the clip.

With reference to Fig. 6, it is noted that assembly of the strip 35 tothe member 20, requires fiexure of the strip 35 to engage the leg 41 inthe aperture 42. Similarly, it requires flexure of the strip todisengage the same from the mounting bracket 26. Thus, the strip 35 maybe assembled to the bracket 20 at the assembly plant prior to theinsertion of the louvre 24, and the assembly may be shipped with thelouvres removed without danger of losing the parts by inadvertentdisengagement thereof.

While a particular embodiment of the present invention has been hereinillustrated and described, it is not intended to limit the invention tosuch disclosure but changes and modifications may be made therein andthereto within the scope of the following claims.
